Summary

Microplastics were sampled in nearshore bathing waters just a few meters from shore — a zone rarely studied due to difficulty accessing it with motorized vessels — and found to contain high concentrations of particles. Land-based plastic waste first encounters and breaks down in this nearshore zone before dispersing offshore. The study fills a critical data gap and highlights that the zone where people swim may have substantial microplastic loads with implications for human exposure.

Only few studies have investigated microplastic pollution at a few meters from shore, mainly due to methodological limitations such as limited access to bathing areas with motorized vessels. Land-sourced plastics first encounter the nearshore, where they effectively breakdown into smaller pieces such as microplastics ( Also see: https://micro2022.sciencesconf.org/427235/document
